The Fool (spoilers for all RotE books, including LST)

I agree, the Fool had very childlike qualities when he was in that particular character and that's how Fitz liked to interact with him. But he was not childlike at all when he was Lord Golden, self-indulgent and pompous perhaps, nor when he was Amber. I think he all but stated on more one occassion that he wanted more of a relationship, more intimate a relationship, than Fitz could handle and for that reason he did not pursue or request it. Now, as mentioned, what that would mean exactly is unclear because again- it was repeatedly implied that the other White Prophets were actually male or female. The Pale Woman even offered to give Fitz children and live as his wife, soooo....
